Audiosurf

I've been a big fan of this game for a while now, and I was curious whether anyone here played/still plays it.
What character do you usually play as? What's your favorite type of music to play?
I play NM/I exclusively, and I mostly play faster electronica songs.

Also, if anyone cares, I've made a few videos and uploaded them on Youtube:

I had an idea today, for anyone who might be interested.
We share song files that we think are cool or fun with other people (via mediafire or bayfiles or something), and other people play that song file and we try to beat each others' scores (posting screenies of the score). Any character could be used, but scores would be by character.
